BACKGROUND OF THE INVENTION

Field of the Invention: The present invention relates generally to straps and harnesses for carrying a portable radio, and more particularly to straps for securing communications devices to belts and harnesses, and still more particularly to a firefighter's magnetic stabilizing (anti-sway) strap for reducing radio pendulation.

Background Discussion: Firefighters and other first responders typically carry communications devices, most commonly a two-way radio. The radio may be holstered in a radio case attached directly to a waist belt, or it may be connected to an over-the-shoulder strap worn either outside or inside personal protective equipment, such as a fire kit including a turnout coat and trousers. When deployed on a shoulder strap harness, the radio is subject to swinging and often at the expense of the user's comfort, ease of use, and occasionally safety.

Anti-sway straps are known, all including spring-biased clips (at best, swivel clips or trigger-snap hooks) at each end of the strap. The clips are adapted for coupling to a turnout gear waist belt and/or a shoulder strap. When the user wishes to attach or to detach the radio holster or case from the belt or shoulder strap, the clip must be opened using the thumb and a finger—which is a clumsy and extremely difficult operation to perform in gloves.

It would be desirable, therefore, to provide an anti-sway radio stabilizing strap that facilitates rapid uncoupling from a user's belt or other harness strap without the need to grasp the clip to attach and disengage it. It is to that end that the present invention is directed.

SUMMARY OF THE INVENTION

The present invention is an anti-sway stabilization strap adapted for use with communications devices suspended from harnesses and/or webbing disposed over or under personal protective equipment, such as turnout coats, for firefighters and other emergency first responders or military personnel.

In its most essential aspect, the inventive anti-sway strap includes an elongate flexible strap, adjustable in its length, having a first end and a second end. A magnetic quick release coupling element is disposed on the first end. A snap connector element is disposed on the second end. And a ferromagnetic element configured for attachment to a harness or waist belt is provided for magnetic coupling to the magnetic quick release coupling element.

In embodiments, the anti-sway strap is paired with a ferromagnetic element configured to connect to a wearer's waist belt or shoulder harness. Also, in embodiments, the ferromagnetic element is a flat disc or plate securely incorporated into a retaining clip, which is preferably a foldable nylon or plastic bar with a snap closure that enables the wearer to slidably secure the clip to a belt. Thus, in use, the wearer may adjust the position anywhere along the length of his/her waist belt according to size and device position preferences. The clip positions the ferromagnetic element over the belt material so that the magnet couples without interference and so that the clip itself does not contribute to sway.

This brief summary statement of the invention broadly sets out the more important features of the present invention so that the detailed description that follows may be better understood, and so that the present contributions to the art may be better appreciated. But there are additional features of the invention that will be described in the detailed description of the preferred embodiments of the invention which will form the subject matter of the claims appended hereto. As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based may readily be used as a basis for designing other structures, methods, and systems for carrying out the purposes of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1 through 5B, wherein like reference numerals refer to like components in the various views, there is illustrated therein a new and improved firefighter radio anti-sway (stabilization) strap, generally denominated 10 herein.

Collectively, the figures show an exemplary embodiment of the inventive strap, which includes a length of flexible material 12 (leather, aramid fiber, polypropylene, PES polyester, PA-nylon, and other fireproof or fire-retardant webbing) having a return portion 14 looped through an adjustment buckle 16. The upper end 18 of the strap is looped over the bar 20 of a rectangular ring 22 on a generally planar disc magnet 24. A bend is formed at a lower end 26, where the return portion 14 loops back on the strap length and has a free end slidingly disposed on and connected over the bar 28 of swiveling trigger snap 30. The adjustment buckle enables the user to adjust the effective length of the strap, i.e., the strap length between the trigger snap and the magnet.

As will be appreciated from FIG. 1, the anti-sway strap extends between and is connected to the D-ring 32 of a radio 34 (or holster supporting a radio). It is coupled to the D-ring at its lower end 26 with the trigger snap 30 and via the disc magnet 24 at its upper end 18 to a suitable ferromagnetic connecting element 36 disposed on a retaining clip 38 clipped onto the waist belt 40 of a user, such as a firefighter FF, which in this illustration is shown encircling the user on the outside of a protective gear. A second anchoring element is provided by another harness strap 42, such as a shoulder strap, as well known in the art.

Looking next at FIGS. 2A-2C, in an embodiment, a retaining clip 44 includes a ferromagnetic connecting element, such as a ferromagnetic plate 46, riveted or otherwise incorporated into the retaining clip 44, which is slidably disposed around the waist belt. This clip may be of the kind described in U.S. Pat. No. 6,823,566, which patent is incorporated in its entirety by reference herein. Such a clip may best be described as an injection molded, heavy duty, reusable connecting clip adapted for attaching modular pouches to modular lightweight load-carrying equipment and pouch attachment ladder system webbings. Use of such a device enables a wearer to position the retaining clip anywhere along the length of the waist belt or other harness strap, such that the anti-sway device can be deployed on and incorporated into nearly any harness configuration. They are manufactured and sold by Tactical Tailor of Lakewood, Wash., USA.

It will be appreciated, moreover, that if desired to have a more fixed location, the ferromagnetic plate may be incorporated into the waist belt itself, thus eliminating the need for an extra element. Indeed, the magnet coupling element may be disposed along the length of any harness strap such that the radio suspension configuration can be tailored to a user's preferences, the only imperative being a two-point connection to the radio with spaced anchor points so as to create a triangular strap geometry [see FIGS. 1, 5A-5B].

In embodiments, elements specifications may include the following: magnets may be neodymium cup magnets comprising round base magnets encased in chrome plated steel cups and bonded to the cup interiors with adhesives. Round base magnets may be termed magnetic cup holders or magnetic cup assembly. Preferably magnets have a diameter approximately ¾ inches and a holding power of approximately 40 lbs. Trigger snaps for the lower end of the strap are preferably standard duty swiveling metal trigger snap hooks. Screws or rivets to couple the magnets to the retaining clip may be ⅛ inch standard slotted screws, though multiple variations are suitable.

Specification variations may be implemented for differing applications, including variations within the personal protective equipment field. For instance, the magnet and ferromagnetic plate may be configured, sized, and of coupling strength sufficient to effectively couple and hold a radio in the attached anti-sway position even when the waist belt is worn under a turnout coat while the anti-sway strap is attached on the exterior side of the side of the coat. This gives the user particular flexibility in donning the PPE kit and entirely eliminates any need for buckle elements outside the coat that can get caught on environmental structure or exposed to heat and flame.

As will be appreciated, the anti-sway strap provides a stabilizing feature that eliminates the shortcomings of conventional anti-sway straps having only clips at the fastening ends. It is an improvement long needed and having a profound practical impact.

The above disclosure is sufficient to enable one of ordinary skill in the art to practice the invention, and provides the best mode of practicing the invention presently contemplated by the inventor. While there is provided herein a full and complete disclosure of the preferred embodiments of this invention, it is not desired to limit the invention to the exact construction, dimensional relationships, and operation shown and described.
